PLATE X. 
This bird, whicli was found at Monterey, approaches very closely to a species lately described by 
Capt. King, from the Straits of Magellan, the Columla Fitsroyii. (Proceedings of Comm, of Science of 
Zool. Soc. p. 15.) The markings, more particularly on the back of the neck of both birds, and on the 
tail, bring them closely together, as well as their general size and appearance. But the vinaceous 
colour, which is found only on the head and lower body of our bird, extends more generally over the 
body of Capt. King’s. The colour of the bill and legs also differs. Our bird is also allied to the 
Colombe Denise of M. Temminck, ( PI. Col. 502,) which probably is the same as Capt. King’s bird.

Being adverse to any change in a specific name, unless where it is decidedly misapplied, I have 
retained the old and well-established name of Gmeliu and Latham, in preference to the new one, 
which M. Temminck proposes for this bird. The objection to a specific name, that it is equally 
applicable to other species in the genus, may attach to any name expressive of a character, according 
as new species are discovered which partake of that character. All names would be thus subject to 
continual change. Even the new name of M. Temminck for the bird before us might be cavilled 
against and expunged, if his objection were allowed to hold good, when other species are found in 
this very extensive group, to exist in the same locality, and partake of the same food.

The birds of this species brought home by the expedition are the same as those to which the 
above name is generally assigned. I am not satisfied as to the specific differences of those northern 
species of grouse which assume the white plumage in winter. But we have not materials sufficient to 
decide the point. It must be left to accurate observation on the living birds, throughout their various 
changes.
